PHP Implementation of Malaysia Payment Interface Access Guide

In Malaysia, common payment gateways include FPX (online bank transfer), Boost, GrabPay, Touch 'n Go eWallet, and so on. Below I will provide a generic PHP implementation framework to help you access these payment gateways.

1. Preparatory work

Before you start coding, you need to:

• Register for a merchant account and get an API key
• Understanding the documentation of the selected payment gateway
• Prepare SSL certificate (most gateways require HTTPS)

2. FPX (Internet Banking) Interface Example

<?php

class MaybankFPXPayment {

    private $merchantCode.

    private $apiKey.

    private $endpoint = 'https://api.maybank2u.com/fpx';

    

    public function __construct($merchantCode, $apiKey) {

        $this->merchantCode = $merchantCode;

        $this->apiKey = $apiKey;

    }

    

    /

     * :: Creation of FPX transaction requests

     */

    public function createTransaction($amount, $referenceId. 

                                     $customerEmail. 

                                     returnUrl, callbackUrl) {

        // FPX usually requires the following parameters

        // amount - MYR amount (e.g. 100.00)

        

        if (!is_numeric($amount) || floatval($amount) <=0 ) {

            throw new Exception("Invalid amount");

        }

        

        // API request data preparation

        

        

        

        

        

        

        

        

        

        $data = [

            'merchant_code' => $this->merchantCode,

            'reference_id' => $referenceId,

            'amount' => number_format($amount, 2, '.' , ''),

            'customer_email' => $customerEmail.

            'return_url' => $returnUrl,

            'callback_url' => $callbackUrl,

            // FPX-specific parameters

            // ... Other required fields...

        ];



        // Generate a signature

        ksort($data).

        $signatureString = implode('|', array_values($data));

        $signature = hash_hmac('sha256', signatureString, this->apiKey);



        

        





        

        

        

        

        

        



 3. Example of Boost payment interface



```php

class BoostPayment {

    private clientId.

    private clientSecret;

    private endpoint = https://api.boost.com.my';
